This .inventionrelates .to water or other liquid depth regulators forreceptacles such astanks or baths, andJhasfor-its object to provide 1meansmwherebv the ordinary overflow may bedispensed with, and whereagivenheight,-.cl1aracterized inthat the by the supply of an exactquantity of' liquid can beensured.

' The present inventioncomprises a liquid depth-regulator for tanks,baths or other receptacles provided with afloat forcutting oil thesupply when the liquid level reaches supply is introduced into thereceptacle through the upper portion of a vertical tubular member openat'its lower end and extending downwards into'the liquid suppliedto thereceptacle, the I float being arranged to operatefreely in the tubularmem' her to close a supply valve arranged at vthe upper portion of thetubular-member, When the water rises to the receptacle. r I p Theinvention will be descrlbed 1n condesired height in the nection with theaccompanying drawings in which Fig. 1 is a sectional front elevation ofa liquid depth regulator embodying vthe invention and Fig. 2 is apartial sectional side view thereof.

In these drawings a is the vertical tubular member or outlet chamber, 1)the valve at the upper portion thereof, 0 the float, The

float 0 operates in an enlarged portion 01' of the vertical tubularmember a, such enlarged portion being connected by screws 02' to anenlarged socket a3 formed onthe,

lower portion of a.

The float 0 is connected to a spindle '01 threaded at its lower end tofit'a corre.

r sided rack 03 adapted to engage the teeth of twopinions '04 and 05rotatably mounted onhorizontal shafts 06 and 07 fixed parallel to eachother across the tubular member a. The opposite sides of the pinionsengage rack teeth formed on the inner sides of a forked member 08; Theupper portion of supplies, respectively.- The chamber theforked member08 extends upwards as arlcentralr rod or spindle 09 fixedat ,its upperend to the valve'bi. By means of the valveb on to its seat. Inthisdevice the pressure of the supply alsoassists the rising-float cinensuring apperfeot closure of the supply valve 6, as by means of therack ;and. pinion mechanism the upward movement ofthe; float causes thedownward closingmovement of the valve in thedirection of-the supply.

The'valv'e b engages a face blformed at the upper end of the tubularmember a and in. the, base of an inlet chamber 222 which extends intotwo oppositely disposed lateral extensions a5 and a6-formed at the topof the tubular membera for'hot and cold water 62 this mechanism when,the-float rises it pulls forms a mixing chamber whereby any'desired-temperature of water in thebath or receptacle can ;-be.;obtained by'varying the ratio of the 'suppliesto the said mixing chamberZ22. The ratio may be controlled automatically by thermostatic apparatusunder the influence of the temperature of 'the water in the bath ortank.

At the other ends of the extensionsa5 and (16 are provided self closingor non-return valves a7" so that shouldeither the hot or cold supply beof a higher pressure than the other it will not force back or interfere.with the supply of the other.- The valves a7 are normally closed bygravity.

The ends of the extensions (15 and a6 are provided with fittings a8 anda9 adapted to be connected .to the hot and cold supply pipes of a bathorother receptacle. In order that the'devioe may be used on hot and coldwater bath taps or the like, of different distances apart, the connectinfittings a8 and a9 are arranged to turn a out vertical axes and arePTOVldBd Wltll return bends (113 having swivel joints (r14 whereby theycan be connected to the taps. r

: On the top of the'chamber 62 is provided a removable cover alO,adapted to give access to the valve Z) and its connections, and 1 onthe. tubular membera are provided two oppositely disposed deliveryoutlet pipes T V I 1,920,062fl all and a12 so that the free flow ofliquid through the devicewill not be ailected by the float. The outletpipes all and 6012 have nozzles arranged above the surface of thepredetermined depth of liquid required.
